SERVSWITCH™ USB AND USB PLUS

3.4Setting the Hotkey Sequence (USB Plus with PS/2 Keyboard Only, Positions 1 & 2)

You can access several of the ServSwitch USB Plus’s main functions (such as CPU- channel selection and autoscanning) by sending commands from a PS/2 type keyboard attached to the Switch’s PS/2 keyboard port (refer to Section 5.4—the Switch cannot recognize commands from a USB keyboard). Each command must start with a “hotkey sequence” (series of keystrokes) that alerts the Switch to interpret the keyboard data that follows it as a command.

The default hotkey sequence is [Ctrl] and [Alt] pressed simultaneously. If any of the applications on computers attached to the Switch require this sequence to trigger important application-specific functions, you will have to either send that sequence to the application from an attached USB keyboard (because the Switch will not recognize hotkey sequences sent from USB keyboards), or you’ll have to change the Switch’s hotkey sequence.

To change the hotkey sequence, move positions 1 and 2 of the DIP switch on the bottom of the ServSwitch USB Plus to your desired setting:

PS/2 Keyboard Hotkeys		Position 1	Position 2
[Ctrl] and [Alt] (default)		OFF (down)	OFF (down)
[Ctrl] and [Shift]		OFF (down)	ON (up)
[Alt] and [Shift]		ON (up)	OFF (down)
No hotkeys (PS/2 keyboard	ON (up)	ON (up)
commands disabled)

3.5 Enabling/Disabling Mouse Switching (USB Plus Only, Position 3)

In the ServSwitch USB Plus’s factory-default state, you can use a three-button PS/2 mouse or IntelliMouse attached to the Switch’s PS/2 mouse port to cycle through the Switch’s CPU channels; see Section 5.5. If you don’t want to use this feature— particularly if it’s going to conflict with mouse-controlled application functions— you can disable it.

To enable mouse switching, move position 3 of the DIP switch on the bottom of the ServSwitch USB Plus to OFF (down, the factory-default setting). To disable mouse switching, move position 3 to ON (up).
